Huge outstanding Navajo sterling silver necklace. The hogan beads are hand soldered with the holes punched from the inside out before soldering. (older style) They are 10mm in diameter. It has 6 huge natural blue turquoise stones set in sterling settings. The surface of the stones has Zuni lapidary work as they have carving. The settings have knife edge stamping and raindrops. Necklace is 23" long, end to end. Front drop is 4" long.  Stone settings range in size from 1 3/4” by 1 1/4” to 2 1/4” by 1 3/4”. It is very tarnished black on the back. I did clean the front surface a bit. Weight: 150 grams. No hallmarks.  Another rare find!
